The San Diego Chargers have placed SS Bob Sanders (knee) on Injured Reserve, ending his 2011 season. In a corresponding move, the team signed free-agent DL Tommie Harris (Colts). Terms of the contract were not disclosed.

The San Diego Chargers have yet to officially sign free-agent FS Bob Sanders (Colts), according to Aaron Wilson, of NationalFootballPost.com. The deal needs to be ratified by the league as a contract language issue is being worked out. "Sanders signing not official yet, but hopefully soon," Chargers spokesman Bill Johnston wrote on his Twitter account. "Stay tuned."

Updating previous reports, the San Diego Chargers have signed free-agent S Bob Sanders (Colts) to a one-year deal, reports The Sports Network. Financial terms of the deal were not disclosed. Sanders, 30, has played just nine games since 2007, and appeared in just one game last season. Since being selected by the Indianapolis Colts in the second round of the 2004 NFL Draft, Sanders has played in more than six regular-season games only twice in his career. His best season was in 2007, when he posted 132 tackles, 3 1/2 sacks and two interceptions, which led to him being named the NFL's Defensive Player of the Year.
